Sea water desalination
Chemical energy is released when the coal burns with oxygen in the air. This energy is used to heat water, which is converted into steam. Not all of the energy is used to heat the water. Some of it is wasted by being transferred as heat to the surroundings. The energy of the steam is used to turn the turbines, but some of the steam energy is wasted.

Electrical energy
Inefficient suction power due to clogged filters or blockages, as well as energy used by the vacuum motor and any additional features such as rotating brushes, are common sources of wasted energy in a vacuum cleaner.
Energy efficiency is the ratio between the useful power, and the electrical power used. If this ratio is - for example - 70%, that means that the remaining 30% of the input power is wasted.
Energy can be wasted through inefficiencies in buildings, appliances, and vehicles, as well as through behaviors like leaving lights on when not needed. Energy can also be used in excess when equipment is oversized for the task at hand, such as heating or cooling a space too much. Additionally, energy can be wasted in the form of standby power consumed by devices that are plugged in but not in use.
It is usually wasted.
it is energy regeneration power plant in which water is used to generate power.water is moving on turbine and then turbine moves so energy stored in the resrvoir yhat is called as hydro power plant reservoir.
In a nuclear power plant, nuclear energy is transformed into heat energy through nuclear fission. This heat energy is then used to produce steam, which drives turbines connected to generators to produce electricity. So, the energy transformation in a nuclear power plant is from nuclear energy to heat energy to electrical energy.
The efficiency of a coal burning power plant is between 35% and 40%. This means that 40% of the energy is used to make electricity and the other 60% is wasted on heat and pollution through cooling towers and smoke stacks. This is the same efficiency that we had in the 1950s.
